Principle Investigator : Ming-Chang Chen 陳明彰
Dr. Ming-Chang Chen graduated from JILA, University of Colorado, Boulder in Physics in 2012. Currenlty he is an Associate Professor at Institute of Photonics Technologies and Adjunct Professor in Physics Department, National Tsing Hua University, Taiwan. He focused his research on demonstrating novel techniques for generating ultrashort femtosecond and attosecond EUV light sources, and their applications in capturing the fastest dynamics in molecules and materials, as well as resolving nano-scale imaging. |

When moving my research career back to NTHU in 2013 spring, I built a EUV&ATTO lab aiming for making a bright, coherent table-top EUV and soft X- ray lasers. My recent research is focusing on generating ultrafast short pulses and understanding the mechanism of high order harmonic generation (HHG) — a coherent process to convert visible/infrared light into light with much shorter wavelength. Simply speaking, when intense UV/Visible/Infrared light is focused into noble gas atoms, the nonlinear interaction between them could give light with tens or thousands of times higher frequency. The spectrum, spatial coherence and brightness of the generated light depend on a lot of parameters like the interaction geometry, the driving laser frequency, and how well the phase matching condition is satisfied. Huge progresses have been made in recent years during my research in NTHU. For example, we first demonstrated and proposed the complete solution for polarization control of isolated attosecond pulses. This new accessible and reliable table-top EUV light source makes a lot of the first possibilities in Taiwan, e.g. providing ultrafast EUV light for Time-Resolved Angle-resolved Photoemission Spectroscopy (TR-ARPES) in NSRRC, and coherent EUV light source for nano- imaging. In addition, he received NTHU as well as EECS Young Scholar Outstanding Research Awards in 2016. |
